Kükürt çimentosu-agrega kompozitleri. genel olarak, hem kükürt çimentosu hem de agrega içeren bir kompozit anlamina gelmektedir. Kükürt çimentosu-agrega kompozitlerinin örnekleri; kükürt harci, kükürt betonu ve kükürt genlesimli asfalttir. Kükürt genlesimli asfalt, asfalttir; yani tipik olarak dolgu maddesi ve bir artik hidrokarbon fraksiyonu içeren bir baglayiciya sahip agrega olup, burada baglayicinin bir kismi, kükürtle ve genellikle de modifiye edilmis kükürtle yer degistirmistir. Sulfur cement-aggregate composites. In general, both sulfur cement and aggregate It means a composite containing . Examples of sulfur cement-aggregate composites; sulfur mortar, sulfur concrete and sulfur expanded asphalt. Sulfur expanded asphalt is asphalt; well typically has a binder containing filler and a residual hydrocarbon fraction aggregate in which some of the binder is combined with sulfur, usually modified sulfur. It has changed location.
Su stabilitesini artirmak için kükürt çimentosu veya kükürt çimentosu agrega bilesimlerinde stabilize edici bir ajan olarak organosilan bilesiklerinin kullanildigi bilinmektedir. Örnegin US 4,164,428'de, agirlikça en az %50 kükürt, bir kükürt modifiye edici (çogunlukla bir kükürt plastiklestirici olarak anilir), ince partiküller haline getirilmis bir mineral askida tutma ajani ve bir organosilan stabilize edici ajan ihtiva etmekte olan bir modifiye edilmis kükürt bilesimi (çogunlukla bir plastiklestirilmis kükürt bilesimi olarak anilir) açiklanmaktadir. Uygun organosilanlarin, R-Si(OR')3 genel moleküler formülüne sahip oldugundan bahsedilmekte olup, burada, R', düsük molekül agirlikli bir alkil grubu ve R, genellikle kisa bir alkil zinciri ile silikon atomuna baglanan en az bir fonksiyonel gruba sahip bir organik radikaldir. Gama- merkaptopropiltrimetoksisilan, tercih edilen bir organosilan olarak belirtilmektedir. In sulfur cement or sulfur cement aggregate compositions to increase water stability It is known that organosilane compounds are used as a stabilizing agent. For example US At 4,164,428, at least 50% by weight sulfur, a sulfur modifier (mostly a sulfur plasticizer), a mineral suspending agent ground into fine particles, and a A modified sulfur compound containing an organosilane stabilizing agent (often referred to as a plasticized sulfur compound) is described. Suitable It is mentioned that organosilanes have the general molecular formula R-Si(OR')3, where R' is a lower molecular weight alkyl group and R is silicon, usually with a short alkyl chain. It is an organic radical that has at least one functional group attached to its atom. Gamma- mercaptopropyltrimethoxysilane is cited as a preferred organosilane.
US 4,376,830'da, bir kükürt çimentosunu ve genlesen bir kilin bulundugu bir agrega içeren bir kükürt çimentosu-agrega bilesimi ve bu tür bilesimlerin hazirlanmasina yönelik islemler açiklanmaktadir. Islemler ve sonuçta ortaya çikan bilesimler, bilesimi katilastirmadan (sogutmadan) önce bilesime belirli organosilan bilesiklerinin eklenmesi ile karakterize edilmektedirler. Uygun organosilanlarin, Z-SI(R1R2R3) formülüne sahip oldugu belirtilmekte olup, burada R1, R2 ve R3, düsük alkoksi gruplari olabilmektedir ve 2, bir karbon atomu vasitasiyla Si'ye bagli bir organik radikaldir ve en az bir erimis kükürt reaktif grubuna sahip olmaktadir. 2, örnegin merkaptoalkil olabilmektedir. Gama-merkaptopropiltrimetoksisilan, tercih edilen bir organosilan olarak belirtilmektedir. Gama-merkaptopropiltrimetoksisilan, çok toksiktir ve çok hos olmayan bir kokuya sahiptir. Elde edilen katilasmis bilesim, su stabilitesini artirmistir. Bununla birlikte, önceki kükürt çimentosu-agrega bilesiminin su stabilitesinin gelistirilmesi için hala ala bulunmaktadir. US 4,376,830 discloses an aggregate comprising a sulfur cement and an expanding clay. sulfur cement-aggregate composition and processes for the preparation of such compositions is explained. The processes and the resulting compositions are processed without solidifying the composition. characterized by the addition of certain organosilane compounds to the composition before (cooling) are being made.
